8.3.4 Instructions for locating and mounting
A FULLY POPULATED VM600 SYSTEM RACK (ABE04X) WITH VM600 CARDS AND
RPS6U RACK POWER SUPPLIES INSTALLED IS A HEAVY OBJECT.
D
EPENDING ON THE NUMBER OF CARDS AND RACK POWER SUPPLIES INSTALLED, A
VM600 SYSTEM RACK CAN BE TOO HEAVY TO HANDLE MANUALLY BY ONE PERSON
AND
THERE IS THE RISK OF INJURY DURING INSTALLATION OR REMOVAL.
S
EE ALSO HEAVY OBJECTS AND THE RISK OF INJURY ON PAGE XVII.
The positioning of the VM600 rack shall allow easy access to the on/off
switch for the main supply.
A fully equipped VM600 rack can weigh 23 kg, so the following instructions
apply:
• Two people are required to carry or mount the VM600 rack in its cabinet.
• Shelves, guide rails and other devices used to support a VM600 rack must
be strong enough to bear the weight of the rack.
For the standard version (PNR: 204-040-100-0xx), separate-circuits version
(PNR: 204-040-100-1xx) and rear-mounting version (PNR: 204-042-100-0xx)
of the VM600 rack, deflection plates (barriers) must be installed both above
and below the VM600.
The barriers installed above and below a VM600 rack are required to
prevent unintentional access to the equipment in order to help reduce the
risk of electrical shock.
In addition, the barrier installed below a VM600 rack is also required in
order to help prevent the spread of fire in the unlikely event that one should
occur. Accordingly, the barrier below a VM600 must be a non-flammable
separation barrier made of metal or a UL94 V-1 rated (or better) material.

LECTRICAL SAFETY AND INSTALLATION ON PAGE XVI.
When inclined plates are used with a VM600 rack in order to deflect airflow
and prevent warm air flowing into a rack, an inclined plate can also function
as a required deflection plate (barrier) if it is made from an appropriate
material. See 8.3.1 Adequate ventilation.
